Video & modem card issues?

[brunsr]

Just built a system: Pentium 4/1.7GHz/512MB SDRAM, Asus P4B motherboard, 300W power supply, slots:
AGP - ATI Radeon All-In-Wonder
PCI 1 - empty
PCI 2 - SB Live! MP3+ 5.1
PCI 3 - USR Faxmodem 56K
PCI 4 - 3Com 10/100 NIC
PCI 5 - empty
PCI 6 - empty
-disabled onboard audio on motherboard by moving jumper
-40GB HD
-DVD & CD-RW
-and lots of fans (power supply exhaust, front intake, rear exhaust & cycloneblower exhaust card fan)

Formatted the hard drive and installed Win98SE with no errors. System comes up in 640x480 mode. Install video drivers and switch to 1152x864. Install modem drivers. Now whenever I boot the PC, the system will run for about 2-3 minutes and then do one of the following: 1) lock up completely (mouse still moves but entire screen is
frozen); 2) screen will go blank and monitor goes into offline mode (but computer is still running); 3) screen will get suddenly very bright and freeze. Keyboard totally inactive, only way to get out is hard boot. No PCI interrupt conflicts present when I look at each device. BIOS settings seem to be correct.

Could this be a video card or modem card issue?

Any help appreciated!!

Could be a variety of things...

Try running the video at a lower resolution. Try unplugging the modem from the mobo - what happens to the video then?

Have you got the latest BIOS update? Have you tried checking the ATI site for latest video drivers. Ditto modem and soundcard drivers.

Try moving the cards around in the slots.

You need to get back to where the system is stable. This may mean uninstalling modem and/or soundcard software, removing cards, etc.

Good luck!
